A thru-wall solar kitchen building or trailer has a vertical oven door (0 in Fig A); and reflector parts (Fig A): 1 is a reflector wall above the oven door; 2 is a box with horizontal or inclined inlet aperture (unglazed or glazed); 3 is a ridged- pyramid base/bracket; 4 is an E and W end adjustable or repositioned at noon; and 5 is the other side of a two-sided trough. Cookware targets (Fig B)include: w-1 roaster pots; w-2 HotPots TM; and w-3 all-glass evacuated tubes. Multi-tube racks rolls/slides in-out thru the oven door into the exterior cooking zone. A five tube rack is illustrated in Fig. C. The tubes are horizontal or near horizontal.

Thru-wall solar kitchen with multi-tube racks roll in-out thru doors into the exterior cooking caustic zone, so that batch after batch can be cooked in a day. The multi-tube racks are within the volume of the exterior nonimaging reflector boxes, avoiding wind, and so that E and W end reflectors (repositioned at noon) flapping in wind gusts could not damage the tubes. The tubes can slip out of the racks for ease of tube cleaning.

Joel Goodman is a research architect living in Wisconsin. After a few solar cooking experiences in the 1970-80s, he began studies of small-mid size solar kitchens using built-in fixed ovens (2003), inserted solar box cookers (2005), and augmented with building size nonimaging fixed reflector troughs with adjustable end reflectors (2007)(2009). Because of outgassing concerns from materials (insulation, glues, etc.) inside of augmented box cookers, and box cookers take up space in kitchens, mid-size kitchen studies began with thru-wall greenhouse type (HotPotTM, etc.) ovens (2006), and recently for small houses with thru-wall greenhouse type ovens combined with improved cook stoves, revealing house plan and solar access planning requirements. Additional studies are for exterior furniture fixed reflectors augmenting box cookers.

March 2014: Reflected nonimmaging concentrated sunlight from a CPC-type trough thru a vertical wall opening to reflectors funnel sunlight upward to the underside of cookware.

March 2014: Converting a sun-facing double-hung window wall for non-snow season cooking and baking. The lower window part becomes the cookware doorway to the exterior concentrating reflectors. The window width influences the inlet size of a reflector ‘box’, securely attached to the exterior building wall. Roof overhang and gutters can limit the height of the upper reflector fixed to the building wall around the upper window part (above the box). The reflector ‘box’ would be removed for the snow season and the reflectors on the double-hung window could be removed as well for daylighting and passive cold season heating.

September 2013:Thru-wall fixed non-imaging reflector concentrator for ovens, cookers, autockaves, etc. A thru-wall fixed nonimaging (NI) reflector concentrator for ovens, cookers, autoclaves, etc. may be a lightweight for the most part attachment to a house or trailer wall. A NI ‘box’ has four creased aluminum-reflector elements attached together, secured to a square based two-angles pyramid-reflector(with grill posts) supported on a bracket(s) structured to the wall. Augmentation is with fixed reflectors attached to the wall, and E and W repositioned reflectors at noon with wind fail-safe design.

October 2012: The adjacent drawing illustrates using a fixed one-sided reflector trough to augment a built-in solar cooker.

September 2011: When a thru-wall cooker counter height is higher, 36 inches/ 915mm above kitchen floor level, and the outdoor ground level is lower, 24-36 inches or more below the kitchen floor level, a more substantial construction is required to support the fixed reflector concentrator, possible with an integrated small storage space/room. And a higher rainwater drain permits water storage with a higher gravity flow.
